CAN ANYBODY REALLY TRUST TOBY?

I see Toby as a deceiving, cunning psychopathic liar. Now someone may say "well you jump the gun" that may be right but believe me I've been there and done that. While smoking a joint with four friends he wrote "Fuck you" on the wall in the boys bathroom. Being questioned by the vice principal with mom at his side Jack insisted he didn't do what was done in the bathroom. When in reality he did do it. Yet him mother still believes him. I hope when the time comes Dwight sets him straight.
